Description
OBJECTIVES:
This experiment involves recording of the electroencephalographic activity of the brain (EEG dynamics) and event related potentials (ERP) during the performance of a visual-orientation perception and visuo-motor tracking task that humans and astronauts may encounter on a daily basis. Within the experiment, five cognitive processes (Perception, Attention, Memorization, Decision and Action) were studied. The stimulus set also contained task-irrelevant novel visual stimuli to allow assessment of electrophysiological correlates of novelty processing. Psychophysical analyses were measured during these tasks. EEG and ERP recordings were also collected to allow the evaluation of the arousal levels of the subjects. In addition to conventional spectral analysis, EEG were quantified with maps of linear and nonlinear complexity. As the novel conditions of microgravity accompanied by a multitude of stressors may place an increased load on the cognitive capacity of the human brain, it was hypothesized that sensory signals and motor responses must be processed and interpreted in a new reference frame.
